Patent JP-S5530808-A (JP)
Title: Forming method of semiconductor area
Inventor: KATOU HIDEAKI
IPC: H01L21/331
Filed: 1978-08-25
Abstract: PURPOSE: To shorten diffusion time without raising the diffusion temperature by simultaneously diffusing two kinds of conductive impurities with reverse conductive types when forming a semiconductor with large resistance by the diffusion method.  
     CONSTITUTION: To the surface of a semiconductor are added both one conductive impurity substance and less amount of impurity substance with the same level of diffusion coefficient and with reverse conductive type to be simultaneously diffused. In this case, the density difference of two kinds of added impurity substance become the actual impurity difference, and the narrowing of their adding amount virtually increases the resistance of the semiconductor area. Since it is not necessary to decrease the absolute amount of impurity substance, sufficient diffusion speed is available to make possible the formation of high resistance area in a short time without raising the diffusion temperature. For example, with the combination of phosphorus and boron, high resistance base area is made by the above process for Darlinton transistor.

Abstract: PURPOSE:To detect the size of an original accurately and to prevent first copy speed from being lowered by controlling scanning start timing in detecting the size of the original so that the quantity of emitted light is increased up to a regulated value before an optical system reaches the rear edge position of the original. CONSTITUTION:Light from the exposure lamp 11 of the optical system 10 is reflected by the original D and received by an optical sensor means 51, wherefrom a signal is outputted in accordance with the optical intensity thereof. The existence of the original D is detected by the quantity of light received by the optical sensor means 51. A position where no original is finally detected is judged to be the rear edge position of the original D, and the size of the original is thereby detected. The scanning start timing in detecting the size of the original is controlled by a controlling means so that the quantity of light emitted by the exposure lamp 11a is increased up to the regulated value before the exposure lamp 11a reaches the rear edge position of the original D in a minimum detectable size. As a result, the size of the original can be detected accurately, while first copy speed can be prevented from being lowered.
